True or false
Explanation:
Statement one is incorrect and statement two is correct
Step by step explanation:
Statement 1: While decoding from DNA to mRNA some rules need to be followed.
for Gene code:
- DNA- 'A' mRNA will be- 'U'
- DNA- 'C' mRNA will be- 'G'
- DNA- 'T' mRNA will be- 'A'
Hence for bases in DNA TGAACCCTT the sequence of bases in mRNA will be ACUUGGGAA.
statement 2: This statement is true because DNA has double helix which is from the nitrogenous bases forming hydrogen bonds between two opposite DNA strands.
